Craft chocolate sells on provenance: the bean, the origin, the maker. That is a story, and a story does not fit on a shelf card next to a sample.
DSD supplied the display running the origin and process content while people taste, with the subscription club offer in rotation. Somebody standing at the table with a square of chocolate in their mouth is the single best moment to explain where it came from and how to get more of it.
Small stand, small screen, exactly the right piece of content at exactly the right second.
